SPECIFICATION forming part of utter! Patent No. 648,662, dated ray 1, 1900. Application flledll'nly 22, 1899. Serial Io. 724,305. we model.)

To all whom it um 1 concern-.-

Be it known that we, Hams Gonons and JACOB TAIZ, residing in the city .and county of Philadelphia, in the State of Pennsylvania,

5 have invented certain new and useful Improvements in \\-'ci ghing-Machines, of which the following is a full, clear, and exact description, reference being had to the accom panying drawings, forming a part of this re specification.

This invention relates to weighing machines, and has for its object to provide a simple and eflicient construction whereby large quantities of coal and like material may be r 5 expeditiously and accurately weighed as rapidly as it is discharged from the deliverywagon. v

The invention is particularly designed for household use, to the end that the weight of so coal delivered to the consumer may be accuratcly ascertained by him.

Accordingly the invention comprises certain novel features of construction and organiz'ations of parts, which will be hereinafter as particularly described and claimed.

In the drawings, Figure 1 is an end view ofan apparatus embodying our invention in its preferred form. thereof. Fig. 3 is a side elevation of the same.

Figs. 4 and 5 are details of the registering mechanism. Fig. 6 isa detail of the locking device for the weighing-receptacle.

' The numeral 1 represents a supportingframe comprising the side members 2, the

5 lower cross-bar 3, and the depending stem 4.

This stem extends into a tubular post 5, risiug from a substantial base 6, and is provided with a suitably-disposed nut 7, by the manipulation of which the said frame may be raised 0 or lowered,asdesired. Journaled in bearings 8 adjacent to the side members is a horizontal shaft 9, to which is affixed at chambered receptacle 10. In the present instance this receptacle comprises two square end heads 11, connected by a tubular hub 12 and four diagonal walls 13, which latter extend from the hub to the respective corners of the end heads, so as to provide four chambers or compartments. These walls are preferably correspondingly curved, as seen, similarly to the blades of a turbine, so that when the uppermost compartment is supplied with material Fig. 2 is a vertical section it will tend to tip or turn the receptacle in the direction indicated by the arrow. The shaft extends through vertical gulde-slots 14 in the side members of the supporting-frame,

so as to be vertically movable therein. flhe' bearings are correspondingly movable,' the same having aflixed thereto vertical rods 15, that extend through and are guided-in latch ally-projecting lugs 16 on the side members. These rods at or near their upper ends are provided with collars 17, between whiih and theunderlyinglugsaredisposedspiralsprings 18, thattend normally to maintain the said hearings in their uppermost position. It will be seen that by adjusting these collars on the rods the tension or pressure of the springs may be nicely regulated. For-this purpose we screw-thread the rods at points above the 79 collars and equip the rods with setnuts 19, by the manipulation of which the requisite adjustment of the collars may be elfected. The shaft is provided near its respective endsIwith a series of radial orifices 20, which correspond 7 5 in number and position with the compartments of the receptacle, and the lugs 16 are provided with depending pins -21, that are adapted to register with these orifices when the shaft and the receptacle thereon are in 80 the raised or normal positiomsnd therebylock the said receptacle fixedly in place. The lower ends of the pins are preferably provided with antifriction-rollersn. The orifices are so disposed that when the receptacle is thus locked the mouth of the upper compartment or chamber is horizontal, or substantially so,

to the end that coal or other material maybe readilyintroduced thereto. During the tilling of the upper compart-ment the receptacle 9c s gradually depressed by the increasing weight against the action of the springs, thus correspondingly withdrawing the shaft from the interlocking pins. When the com rtment has been supplied with s predeternszcd quantity of material, the shaft is entirely disengaged from the pins, whereupon by virtue of the conformation of the walls of the compartment the receptacle is tipped forward by the weight of its contents and thelattcrtlmsroo discharged therefrom. Inthis movement the receptacle makes a quarter-turn, and the snececdingorifieesln theshatt then belnglirrcgister with the pins the receptacle is re to its raised or normal condition, so as to lock the then upper compartment in position for the reception of the coal, &c. When a given quantity of material has been supplied to this compartment, the receptacle is again depressed and its contents discharged aebefore, and so on in continuous succession the compartments are supplied and discharged.

In order that the revolutions of the map tacle may be indicated and the weight of the material received and discharged thereby be accurately determined, we provide a registering mechanism whose operation is controlled by the descentof the receptacle. So'far as the particular construction of this mechanism is concerned our-invention is not restricted thereto, as obviously any other appropriate means to the same end may be substituted therefor. f

' In the present instance one of the sleeves or bearings for the shaft 9 is:extended beyohd the end of the latter and i s provided with a suitable casing 23, in which the registering mechanism is contained. On a stud-shaft 84 in this casing is loosely mounted apinien 25,

' with which engages a dependingrack 26 on the adjacent lug 16 of the supporting-frame, whereby when the receptacle isdepressed, as above described; the said pinion is positively rotated. On this stnd-shaft is also loosely mounted a pinion'i'l', which is geared with a spur-wheel 38 m an upper stud-shaft 29, the

hub of said wheel being provided with an index or pointer 30,;that rotates about a suit.- ably-graduatcd dial '3} in the casing. The pinion 25 is-so-connected with the pinion 27- that the latter will be'retateil onlyduring the descent of the-receptacle. To this end the pinion 27 is provided with a peripherallytoothed collar 28,- which is fitted in an amid-- lar groove in thc-face-of the,pi nion 25, and small antifrictimr rdllers 39* are interposed between the-opposing edges of the collar and the groove..- The teeth of the collar are inclined, as seen, so-tlrat in themtation of the pinion 25 during its de'sccnt the rollers will bind the two pinions together, andjin the reverse rotationof the pinion 25 during its ascent the rollers will roll loosely against the teeth. As.- will. be observed, the extended sleeve or bearing is suitably pcrloratcdl'or the pcmage oftIre-Iocking-pin.

As a simple and cflicient means whereby the material-shall be delivered in uniform quantities hr the successive compartments of the receptacle we arrange above the latter a hopper :tlr,into which-thematerial is lirst delivered. Tlris hoppcr comprises two sections, one of p hichzis. fixed a'r'ul'llhe other hinged thcrcto .so that the loweror discharg iug portion olihghopper may be opened a'nd closed at pmttleicrurintkintefl'als in respect to the prisitioir'iif the underlying receptacle.

'lhc liacd scetionol'i the hopper is supported by upward cflcn ior rs f the sido'piccw of the main frarlre, \v lrrlc tho-othcr section is pit'ulml, as af'tilflo said lixcd sect ion. Normally the lower end of the hinged section is closed by the action of an exteriorly-arranged spring 32,aflixed thereto and to one of the frame extensions. Each of 'the sections of the hopper is provided with projecting stems 33, carrying antifriction-rollers' 3%, between which extend cam-bars 35, that are affixed to the upper ends. of the respective rods 15. These bars are provided with parallel edges 86 and with inclined portions 37, which are so relatively arranged that when the race tacle is in its uppermost position the parallel edges bear against the rollers 3t and maintain the hinged section of the hopper open to permit the contents thereof to fall into the underlying receptacle and that when the receptacle by the weight of its contents approaches its lowermost position the inclined portions of the bars engage the rollers on the hinged section and perinit the latter to'swing inward, thus cutting 0d the feed to the receptaele. In the succeeding ascent of the receptacle the hinged section is again opened by the vertical edges of the cam-bars.

The coal or other material to be weighed is shoveled or dumped into the hopper and thence delivered to the successive'compartments of the receptacle and progressively weighed thereby, the aggregate weight being indicated by the register, as above explained.
